回复 20楼 sheeboard
week_=df_['date'].map(lambda x:x.isocalendar().week)运行上面的就弹出：AttributeError: 'tuple' object has no attribute 'week
以下是引用sheeboard在2023-5-10 15:28:56的发言：
import pandas as pd
def get_week(x):
return x.isocalendar().week
df=pd.DataFrame(pd.date_range("2023/04/01","2023/04/30"),columns=['april'])
df['week']=df['april'].apply(get_week)
参考

df['week']=df['april'].apply(get_week)

就是把你这个复制过去，也是弹出这样的错误！
